在炎症反应的初始阶段,白细胞沿内皮细胞表面边缘滚动,这一过程主要由选择素及其配体介导。个别选择素突变的小鼠没有表现出自发性疾病,炎症反应轻微或可以忽略不计。相反,我们发现,两种内皮选择素(P和E)零突变的小鼠出现了白细胞黏附缺陷的表型,其特征是皮肤黏膜感染、浆细胞增殖、高丙种球蛋白血症、在加入或不加入肿瘤坏死因子-α的情况下提睾肌静脉中白细胞严重滚动的缺陷,以及对腹膜内肺炎链球菌腹膜炎的反应在4小时内没有中性粒细胞迁移。这些小鼠为选择素在体内的功能重要性提供了强有力的证据。
During the initial phase of the inflammatory response, leukocytes marginate and roll along the endothelial surface, a process mediated largely by the selectins and their ligands. Mice with mutations in individual selectins show no spontaneous disease and have mild or negligible deficiencies of inflammatory responses. In contrast, we find that mice with null mutations in both endothelial selectins (P and E) develop a phenotype of leukocyte adhesion deficiency characterized by mucocutaneous infections, plasma cell proliferation, hypergammaglobulinemia, severe deficiencies of leukocyte rolling in cremaster venules with or without addition of TNF-alpha, and an absence of neutrophil emigration at 4 h in response to intraperitoneal Streptococcus pneumoniae peritonitis. These mice provide strong evidence for the functional importance of selectins in vivo.
